Switching off engine.renderEvenInBackground in Sandbox?

From a quick look at the source code, my understanding is that renderEvenInBackground defaults to true.

I have a number of browser tabs hosting BJS content opened, and I’d like to ease the load on my poor computer when I am not actively working in those tabs :slight_smile:
I can switch off renderEvenInBackground in my own code and in the PGs, but I’m not sure if I can do that in the sandbox, and if so, how.

Side question: what is the rationale behind defaulting to true?

For the sandbox, you can do in the browser console:

BABYLON.Engine.LastCreatedEngine.renderEvenInBackground = false

I think it’s true by default because as soon as a tab looses the focus it freezes the window if renderEvenInBackground = false and I don’t think it’s what we want in general: in dual screen working, often you have a tab of the browser opened on one screen and something else on the 2nd screen, and you want the scene to render even if the tab hasn’t the focus.

Amazing trick! Many thanks!

I guess that makes sense. I just have the bad habit of opening a bunch of tabs with more or less heavy PGs in it, so that, combined with a couple of scenes being reviewed in the sandbox, plus the app in development… Fine on a good pc. Less fine on the cute laptop that I have to use right now :slight_smile:

Would it make sense to have some sort of user settings for the Playground and the Sandbox, that would systematically overrides the apps’ defaults?
